Application led January 8, 1916. Serial No. 71,0?83.

To all wlw/m, t may concern Beit known that l, MARC BIRKIGT, citizen ofthe Republic of Switzerland, residing at BoisfColombes, Department of Seine, France, have invented certain new and vuseful Improvements in Carbureters, of which the following is a specification.

This invention relates to carbureters, particularly to multiple carbureters, that is to say those comprising twofor more suction branches, each provided with'k its sprayer or sprayers and parts for regulating the supply to independent engines or to lcylinders or groups of cylinders of one and the same engine.

The invention has yfor lits object to make it possible to arrange apparatus of this kind so as to enable the output of the sprayers in each of the suction branchesof the said apparatus to be simultaneously regulated by means of a single control.

The invention consists, in inserting an obturator between the constant level tank and the sprayer or sprayers corresponding to each suction branch, and in providing the said obturators with means for simultaneously actuating them.

The invention comprises certain other arrangements, more explicitly referred to hereinafter.

The invention will be understood from the following description as well as from the accompanying drawing in which Figure 1 shows, in section on the line 1 1 of Fig. 2,' a portion of the carbureter; Fig.

. 2 shows the same carbureter in plan., in section on the lines 2-2 and 20e-2 of the Fig. 1. Fig. 8 shows the same carbureter in section on the line 3-3 of Fig. 2.

The carbureter is provided with a constant level tank a, two suction branches b1 b2, two sprayers c1 c2 opening respectively into each of the said branches and both supplied direct from the constant level tank a.

The carbureter is built in the usual manner, care being taken to connect each sprayer, to the inner chamber of the constant level tank by means of an independent conduit e1 c2 provided in the bottom of the said vconstant level tank.

The ends which open into the inner chamber of the constant level tank a are so dimensioned or gaged that, irstly the output of the sprayers is unable to exceed a given value, and that secondly, the output of one of the sprayers is exactly the same as that the stem 0.

f and has provided therein two gaged openings g1 g2 of the same diameter as the gaged portion of the conduits c1, e2 so that after the piston has beenput in place, it is possible to bring the openings g1 g2 in registering alinement with the conduits e1 and e2.

The plug z' is threaded into one end ot the bore 7 and a helical spring h, arranged in the opposite end of said bore, having one of its ends bearing against a cap or closure for that end of the bore and its opposite end bearing against one end ot the piston g, serves to normally maintain the other end of said piston against the inner end of the plug ff, so that the opening g1 and g2 of the latter will register with the conduits c1 and e2. A rectangular tongue g projecting from said piston extends into a correspondingly shaped passage pin the plug 2'-, thus preventing the piston from rotating about its 'axis and insuring an accurate registering of the openings g1 and (/2 and the conduits el and e2. The plug a' is further provided with a threaded bore g extending as a continuation of the passage p and in which is threaded An operating lever j is connected with one ot the stems 0 whereby the latter may be moved longitudinally in the passage p, the tongue go being engaged by one end of the stem. Thus it will be readily understood that when the output of the sprayers is too large the amount may be varied by actuating the lever y' which rotates the stem 710 so that it will act upon the tongue go of the piston against the action of the spring 7L and shift the piston g to close the conduits e1 and e2 to a desired ex tent. It is also to be understood that the sprayers c1 and c2 may be provided with a plurality of sprayer nozzles and also that two or more sprayers could be mounted in each suction pipe. In this way, the considerable advantage is insured that the carbureted mixtures are exactly the same in the two suction branches, and are always regulated simultaneously.

Obviously, the invention is not limited to that method of carrying it out which has been more particularly described, but com prises any modications. Y

Having now particularly described and ascertained the natuie of my said invention and in what manner the same is to fbe performed, I declare that what I claim is l. A oarbureter, comprising, a supply chamber, a plurality of sprayers having independent connectionsy with 4 said supply chamber, and an obturator interposed .in said connections between the sprayers and said lChamber fQl :simultaneously v Contrpb ling the passage of Huid throivigh said connections, said obturator being .provided with a plu 1ality `of openings adapted to register with the' passages of said connections.

2, ln a carburetei, the combination ,with

the plurality of ysuction dfucts, a supply chamber, a spraying ,device for each .suction duct `and having an independent Connection with. said supply cli-amber, and :an obturator arranged in said connections between lsaid spraying devices and supply cli-amber for simultaneously controlling the supply fluid .to said spraying devices.

3Q A Carbureter, comprising, a Huid supply chamber, a ivilurality of sprayers, a duct connecting each sprayer with the supply chamber, an element having a bore therein extending transversely to said ,ducts and intersecting the saine: an obturator arranged in said bore and having a plurality of passages 'therein adapted to register with the passage of the ducts, and means for moving said iobtiuaztor insaid bore whereby the supply of fluid from said supply chamber to 'said sprayer is simultaneously controlled.

el. A carbureter, comprising, a fluid supply voha-nilber, a plurality of sprayers, a fduct connecting the sprayers with the supply Chamber,` an element having a bore therein extending transifersely to sai-d duct and intersecting thg'e sain-e, ain obturator slidably disposed iii said bore and having a plurality of passages therein to normally Vregister .with the ducts, a member tl'ireaded in said bore and engageable ywith one end of v.said obturator to move the latter the bore for sifinultaneously Controlling the passage of tliiid from said supply chamber to said sprayers when. sa-id lmember is rotated, and Afa rspring engaging with the other end of said obturator and to hold the same in eng-agement with said ytlireaelecvl member and for returning said obturator to its no1-mal position,

ln testimony whereof I have hereunto set my hand in presence of tivo subscribing witnesses.
